Abstract: ABSTRACT OF THE DISCLOSURE           An optical waveguide having a first cross section is thinned to constitute a thinned portion having a second cross section, as long as a predetermined length.  The surface of the thinned portion is contacted with a laser glass member doped with a rare earth element, such as Er.  Due to the thinned diameter' the optical fiber is optically coupled with the laser glass mem-ber.  A pumping light is input either into the optical waveguide together with a signal light or directly into the laser glass member.  Signal light coupled from the thinned portion to the laser glass member is amplified by stimulated emission of the laser glass.  The thus amplified signal light is coupled back  to the thinned portion so as to propagate along the optical wave-guide.  The thinned portion can be as short as several centimeters compared with ten meters to more than one hundred meters for a conventional optical amplifier.  In the optical waveguide where the pumping light is directly input to the laser glass member, a complicated multiplexer is not necessary, resulting in a reliable operation of the amplifier.

Abstract: The fill time of a clutch in an automatic transmission is determined from empirical data embodied in look-up tables which relate the effects of pump speed and fluid temperature on the fill time. Calculations are made for a baseline clutch and are multiplied by a volume ratio for a particular clutch. The effect of fluid temperature on leakage is tabulated and used with the pump speed to determine the effective pumping speed.  The effects of fluid temperature on viscosity and oil flow rate are determined and used to adjust the base fill time for high pumping speeds.  The fluid retained in a clutch cavity from a recent application and not fully exhausted is also taken into account.

Title: Method of fabricating highly lattice mismatched quantum well structures

Abstract: A METHOD OF FABRICATING HIGHLY LATTICE   MISMATCHED QUANTUM WELL STRUCTURES                             ABSTRACT        A  method  of  fabricating  a  semiconductor heterostructure includes the growth of a quantum well active region that is highly lattice-mismatched relative to a substrate.  A buffer layer having a thickness above a critical value is grown on the substrate whereby the stress due to a lattice constant mismatch between the buffer layer and substrate is relieved through the formation of misfit dislocations.  A strained superlattice structure is grown on the buffer layer in order to terminate  any upwardly-propagating dislocations,   An unstrained barrier layer is subsequently grown on the superlattice structure.  The fabrication method concludes with the growth of a quantum well structure on the unstrained layer wherein a lattice constant mismatch between the quantum well structure and the unstrained barrier layer is  smaller than the  lattice constant mismatch between the quantum well structure and the substrate.  As a result, only a fraction of the stress due to the large lattice mismatch between the quantum well structure and the substrate is accommodated by coherent strain in the quantum well structure, while the remainder of the stress is relieved through the formation of misfit dislocations spatially separated from the quantum well structure.
